FLEK heat pump

Brief overview of the Fulek heat pump

Thermal energy pump is a new type of technical equipment that converts power into thermal energy. This high-speed heat exchange technology is the principle of Nantong Fleck's application of fluid mechanics, which makes the fluid produce a large number of tiny bubbles in the high-speed cavitation generator, and then continuously produce strong micro-explosion phenomena such as expansion, compression and collapse in the vacuum negative pressure. The explosion process takes less than 6‰ seconds and instantly releases energy to raise the liquid temperature to the boiling point, at the same time, due to the "cavitation effect", the material composition and scaling conditions that are easy to scale in the water are destroyed. Therefore, the impurities in the water will not agglomerate and scale due to the friction and temperature of the water molecular chains, and it will not produce turbulence at high speed kinetic energy. The high-temperature water produced by the thermal pump is transported to the storage tank, pumped by the high-temperature water to each heat sink, and then returned to the storage water tank for secondary circulation, and the thermal energy conversion efficiency of the thermal pump can reach 95%.

The working principle of Fulek heat pump

The working principle of the Flecker heat pump is a multi-stage heat instantaneous heat transfer device composed of a hydraulic cyclone cavitation heat energy generator and a high-speed vortex ultrasonic heat energy generator. In the high-speed drive of the motor, the liquid under the action of the thermal cavitation generator continues to get high-speed shear, mutual collision, friction impact in the formation of micro-bubbles continue to grow, expansion, compression, collapse and other cavitation micro-explosion process. The time of this instantaneous explosion process is not more than 6‰ seconds. Due to the ultra-fine jet generated by the cavitation bubble in the sharp collapse, this ultra-fine jet will produce ultrasonic cavitation and radiate sound waves into the liquid during the injection, and the frequency is generally in the ultrasonic band of 16KHz-100KHz. The high intensity optical radiation (such as laser) generated by this optical cavitation ultrasonic wave segment phenomenon continuously cuts the cavitation bubble, which makes the growing tiny bubbles bear the negative pressure around the negative liquid, and makes the bubbles compress, collapse, explode and other air effects instantly. The energy released in this process makes the tiny droplets reach the boiling point state instantly and circulate continuously. Flak thermal energy pump not only has high thermal energy conversion efficiency, but also has the characteristics of no pressure, no scaling, simple operation and reliability in operation, which is favored by the majority of users. The thermal energy technology can also achieve modular combination with good applicability.

FLEK heat pumpofapplication technology

The application technology of thermal energy pump heating can better solve the problems existing in electric boilers. As the thermal energy pump has no requirements on water quality, it saves the chemical water treatment system, reduces the related investment and site and eliminates the daily maintenance cost of boilers and pipelines. The main internal component of the thermal energy pump is one or several cavitation generators, and the high-temperature water pump can be used for water system circulation in heating; combined with a hot water storage tank can realize the heat storage cycle heating, can also be automatically controlled according to the change of return water temperature. At the same time, the thermal energy pump realizes the heat storage heating technology such as decentralized energy storage and decentralized heating. The most important thing is that the equipment is not a pressure vessel. Although the cavitation phenomenon is formed by the water pressure produced by the cavitation device, the normal pressure is restored immediately after cavitation, and there is no standard for the use of pressure vessels.

　　The heat pump can not only be used to heat water, but also to heat high temperature heat transfer oil, chemical additives, etc. Flecker heat pump is a fully enclosed pipeline for physical cavitation heating, there is no flammable and explosive electric energy heating, open flame heating and other phenomena, and the liquid temperature rises rapidly under the motor drive, such as heat transfer oil temperature can reach 190 ℃ and the heat transfer speed is extremely fast.

　　Thermal pumps can also be used in conjunction with renewable energy systems, such as night-time trough power and storage compensation for solar and ground-source heat as peak-shaving supplementary heat sources. First of all, the use of kinetic energy heating technology should consider the night trough electric heat storage. When the change of ambient temperature limit causes the peak heating load of the building to change and the heat storage heating capacity is insufficient, the power during the peak period is then used for adjustment. Heat pump heating technology can also be used in a variety of specific occasions, such as alpine regions, islands, oil by the heating of flammable and explosive materials, staff heating and so on has great significance.

Examples of applications of thermal pumps

1. Heating can be carried out according to the actual utilization time of the building. One thermal pump model: RNB-40, motor power: 45kw, low-valley electricity consumption: 8 hours. The stored heat can meet the needs of ~ 800m ² office heating, ~ 500m ² residential heating and ~ 600m ² commercial facilities heating.

2. A gas station of Sinopec has a construction area of ~ 800m2, using a thermal pump, model: RNB-40, motor power: 45kw, a 4m insulated water tank, forming aRegenerative heating system. The gas station uses the low-point electricity at night to run and store heat, heat the water tank to 90 degrees C for insulation, and use these hot water for heating during the day. When the weather is too cold, the heater is started to compensate for part of the energy during the day, and its cost is significantly reduced.

3. Use the heat pump to produce domestic hot water with low-valley electricity. One heat pump model: RNB-40, motor power: 45kw, low-valley electricity consumption: 8 hours. The stored heat can meet the shower needs of 250~300 people,

4. It is also convenient to use heat pump in swimming pool. Generally, the average loss of swimming pool is about ~ 2 ℃ per day. Different unit configurations can be selected according to different swimming pool water consumption. The water temperature can be increased for heat preservation at night when electricity is used in low valley. The water temperature can also be heated in low valley and flat peak sections.

Examples of the application of the Fulleck heat pump

1. Independent buildings with large and high cost for urban central heating pipelines or central heating auxiliary supporting projects, including: residential buildings, office buildings, factories, villas, military barracks, border outposts, field commands, etc. Heating and bathing.

　　2. Energy conversion, such as power generation, waste heat recovery, refrigeration and heating, and energy storage; multiple modules can be connected in parallel.

　　3. Units with high requirements for environmental protection and energy conservation, such as: natural scenic spots, tourist areas, airports, ports, Sinopec gas stations, oil depot systems, railway systems, field exploration operations and other facilities for heating.

　　4. For oil pipeline heating, oil well cleaning, and can be directly heated to antifreeze, high temperature diversion oil, etc., the temperature can reach 90-200 degrees.

　　5. Provide heating or heat source for modern light (sea) water aquaculture ponds, swimming pools, bathing and other facilities.

　　6. The product has no special requirements for the original pipes, radiators and water quality. It is suitable for heating in various buildings. It can also be used for regenerative heating to save electricity.

　　7. The new heater technology of converting electric energy into heat energy is adopted to carry out heat storage heating of low-valley electric power in the way of distribution system for centralized heating area. Due to the method of supplying heat energy in sections and lines, energy loss cannot be generated in the intermediate link of heating, thus achieving flexible and convenient adjustment, heating and flexible heating, and actually saving, reducing emissions and increasing economic benefits.
